Solution Overview

Problem

Existing 5GNC solutions for establishing calls between devices with associated applications face challenges such as high bandwidth consumption, ecological impact, increased costs, and user experience issues due to screen sharing and software download requirements, which can lead to jitter and latency.

Innovation Solution

A method involving the establishment of an IMS call session with a data channel, downloading specific applications to both devices, and synchronizing interactions through the data channel to reflect user interactions, using synchronization information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If screen sharing is used to enable interaction between call parties, then the called party can view the caller's application screen, but bandwidth consumption increases significantly

Engineering Contradiction:

Improveinteraction capabilityVSAvoidbandwidth consumption

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential interaction data (click events, input text, navigation actions) from the full screen sharing stream. Instead of transmitting the entire video stream, only the critical interaction elements are captured and transmitted through the IMS data channel, dramatically reducing bandwidth consumption while maintaining interaction capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates a simplified copy of the interaction experience by transmitting structured data representations of screen interactions rather than the actual video stream. The called party's device receives and renders these interaction copies, providing the same functional capability with minimal bandwidth usage.

Inventive Principle:

Principle #26Copying

2Speed

If video streaming is used for screen sharing, then real-time visual interaction is achieved, but network load and energy consumption increase

Engineering Contradiction:

Improvereal-time interactionVSAvoidnetwork energy consumption

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The patent changes the data transmission parameters from high-bandwidth video streams to low-bandwidth structured interaction data. By transforming the interaction representation from visual frames to compact event data (click coordinates, text inputs, navigation commands), the solution maintains real-time interaction speed while minimizing energy consumption across the network.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If both parties need to interact to decide on downloading software, then collaboration is improved, but call establishment complexity increases

Engineering Contradiction:

Improvecollaborative decision makingVSAvoidcall establishment process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal interaction framework that handles multiple collaboration scenarios (software download decisions, support interactions, joint problem-solving) through a single standardized mechanism. The same IMS data channel and interaction data structure support all collaborative needs, avoiding the need for separate complex protocols for each scenario.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Method for a caller device to establish a call with a called device. The method includes: detecting a call to the called device; placing an IMS call session and establishing a data channel; downloading specific applications to the caller device and called device; and during the IMS call session, monitoring interactions with the caller and called devices, and if an interaction is detected, transmission, from this device to the other device, of synchronization information reflecting the interaction through the data channel.
